Product Description

What is ‘Safety Roller?’

• ‘Safety Roller’ is a safety fixture that prevents drivers and passengers from fatal accidents by not only absorbing shock energy but also converting shock energy into rotational energy.
• ‘Safety Roller’ needs to be installed at sites where vehicles are exposed to frequent accidents.
• ‘Safety Roller’ will safely lead a vehicle back to the road or stop the vehicle by absorbing shock energy.
• ‘Safety Roller’ will effectively function for drivers to properly control vehicles with its noticeable color and self-luminescence

  Features

• LED guide Lamp (powered by solar energy)
• Two Pieces (easy to replace, easy to adjust)
• Reduce speed by stopper board
• Guide reflective leads a driver to drive safely
• Recyclable material (eco-friendly)
• Less poles (1pole per 2m). Less cost
• Help a vehicle turn back to the road by its spinning when the car crashed the rollers laterally.
• Minimize fatal damage of people and vehicles by absorbing collision shock.
• Reduce costs in repairing and maintenance due to Roller’s resilience.
• Safety Roller is installed using existing axis poles of the guard rail. (for domestic)
• Stopper boards help prevent larger accidents by slowing down Roller’s spin

 How Safety Roller Works?

1. Roller absorbs collision shock (shock energy -> rotational energy)
2. Front rail absorbs 2nd shock
3. Back rail absorbs 3rd shock
4. Metal pipe inserted in to strengthen post.

2. Curved Ramp
3. Diverging Point
4. Curved Tunnel
5. Curved Downhill
6. Passge Intersection
7. School Zone
8. Danzer Zone etc.
